The GB/T 31929 standard delineates a set of specifications for straight seam welded stainless steel pipes ideally suited for shipbuilding applications. These pipes are specially designed with a focus on durability, corrosion resistance, and high performance. The key features of these stainless steel tubes are their exceptional strength, longevity, and ability to withstand harsh marine environments.
| Element | Composition (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Silicon (Si) | ≤ 1.00 |
| Manganese (Mn) | ≤ 2.00 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 |
| Chromium (Cr) | 16.0-18.0 |
| Nickel (Ni) | 10.0-14.0 |
| Nitrogen (N) | ≤ 0.10 |
| Property | Value |
|---|---|
| Tensile Strength | ≥ 520 MPa |
| Yield Strength | ≥ 205 MPa |
| Elongation at Break | ≥ 35% |
| Hardness (HV) | ≤ 200 |
The stainless steel tubes that conform to GB/T 31929 are typically comprised of austenitic stainless steel. Common steel grades include 304 and 316 stainless steel.
Primarily intended for shipbuilding purposes, these straight seam welded stainless steel pipes find applications in marine environments due to their exceptional resistance to corrosion and extreme temperatures. They are suitable for various ship structures, pipelines, and critical marine systems.
In addition to the standard grades, alternative stainless steel materials that could be considered for similar applications include duplex stainless steels like 2205, 2507, or super duplex stainless steels, providing enhanced strength and corrosion resistance properties compared to austenitic stainless grades.
